The political evolution in Chile seeing from three different times: 1937, 1947 and 1970. A film that shows how a revolution cannot be accomplished by electoral means, and how the wealthy class will always attempt to destroy that revolution, with the help of the armed forces, as soon as their privileges are threatened.
